| Abstract: | Japonica rice varieties from cold zone were used in this experiment to study the milled and physical quality properties.By principle component and cluster analysis,9 varieties which have better synthetic quality properties,were sifted out from the tested rice population,and the tested population was divided into 4 classes.Parents of crosses should be selected between different classes,meanwhile the mutual complement of the principal component should be considered.$$$$ |
